Buttercream Frosting

By author Dish Ditty

Ingredients

  • 1/2 cup Shortening (like Crisco)
  • 1/2 cup Butter (softened)
  • 1lb Powdered Sugar
  • 1/4 cup Water
  • 2 teaspoons Vanilla

Note

VEGAN OPTION: Substitute butter for a butter flavored vegetable spread (make sure it doesn't have milk solids)

LEMON ICING: Add the juice of one lemon to the frosting for a strong lemon flavor or 1/2 a lemon for a light lemon flavor. Add yellow food coloring to make a light yellow color.

Directions

Step 1
Beat butter and shortening until fluffy. Add vanilla and 1/8 cup of water. Beat until well combined. Using slower speed on mixture, slowly add powdered sugar. Increase speed to high and beat at high for about 5 to 10 minutes or until light and fluffy. Add more water to thin and more powdered sugar to thicken.

I find that using the full 1/4 cup is the perfect balance for icing cakes, but I tend to add more powdered sugar to make it slightly thicker for decorating.


Many buttercream frosting recipes use milk (see Wilton’s Buttercream) which will spoil if not refrigerated.  Real Simple’s article explains why butter doesn’t need to be refrigerated:

Butter does spoil, but much more slowly than fresh (unfermented) milk products, such as, well, milk. The reason? “Most butter contains added salt, which impedes the growth of spoilage bacteria,” says John Bruhn, a dairy-foods processing specialist at the University of California at Davis.

Before I was born, my Grandma took a couple cake decorating classes through Wilton.  I still have her original Wilton decorating book with her notes modifying Wilton’s Classic Buttercream Recipe.

After my grandma learned to decorate cakes, she made the most amazing cakes for us. For my sister Suzie’s 16th birthday, she made her an amazing Cinderella’s Castle cake. I was very little at the time, but I remember being in awe looking at the detail she put into that cake.

She taught my dad the tricks of the trade and then later, he taught me. I still haven’t made a Cinderella Cake, but maybe one day I will.

So, use this buttercream frosting for cupcakes, or for a super intricate decorating project. Either way, this recipe will not disappoint.

  • Thanks Vivian, I don’t have anything like this from Grandma Prosnick. When I took some Wilton cake decorating classes a few years ago the instructor relayed a few things about icing that I had not considered. If you want a truly white Buttercream icing (lends to brighter colorings and whiter icing) use 1 cup solid white vegetable shorting (Crisco) and 1 tsp. Wilton Flavoring (vanilla, almond, or butter – sometimes I use 2 tsp.). Pure cane confections’ sugar creates a better icing consistency than powdered sugar. A pinch of salt is optional. If you want Chocolate Buttercream icing add 3/4 cup cocoa or three 1 oz. unsweetened melted chocolate squares and an additional 1 to 2 tbsp. water. She also said to use 1 tbsp. Meringue Powder. As you know the more confections’ sugar you use the stiffer the icing. I normally add a little water at a time to ensure I get the consistency I want; depending on what I’m doing.

    • Yep! All those are right. I rarely need a ‘pure white’ frosting. The buttercream frosting as I posted is usually perfect for most cakes. I have some other recipes for meringue frostings/etc. I’ll slowly start adding them. If you have any of grandma’s recipes or recipes from your childhood, let me know and I can post them 🙂 I’ve always used powdered sugar just for convenience and have found it to work well for my needs.

  • Thank you. I have to make cupcakes for a meeting. My friend had emergency surgery and I am stepping in but this is really short notice. I think your frosting recipe will be perfect.

    • The easiest way to do that would be to add coconut extract in addition to or instead of vanilla. Instead of water, you can use coconut milk as well. Then, after decorating the cake, I would top it with toasted coconut.
